The basic problem of linear programming is to minimize (or maximize) a linear function of a finite number of variables constrained by a finite number of linear inequalities. From a mathematical point of view the subject may be regarded as being divided into two areas. One is primarily analytical and deals with certain questions of duality and consistency. The other is algorithmic and is concerned with computational questions and methods.

AbstractIn this work, an extension of the strain energy for fibrous metamaterials composed of two families of parallel fibers lying on parallel planes and joined by connective elements is proposed. The suggested extension concerns the possibility that the constituent fibers come into contact and eventually scroll one with respect to the other with consequent dissipation due to friction. The fibers interact with each other in at least three different ways: indirectly, through microstructural connections that could allow a relative sliding between the two families of fibers; directly, as the fibers of a family can touch each other and can scroll introducing dissipation. From a mathematical point of view, these effects are modeled first by introducing two placement fields for the two fiber families and adding a coupling term to the strain energy and secondly by adding two other terms that take into account the interdistance between the parallel fibers and the Rayleigh dissipation potential (to account for friction).

It is well known that in many orders of typically winged insects species occur which in the adult stage are apterous or have the wings so reduced in size that flight is impossible. Sometimes the reduction of wings affects one sex only, as in the case of the females of certain moths, but in the majority of cases it is exhibited by both sexes. In many instances wing dimorphism occurs irrespective of sex, one form of the species having fully developed wings and the other greatly reduced wings. In some species the wings are polymorphic. The problem of the origin of reduced wings and of other functionless organs is one of great interest from the evolutionary point of view. Various theories have been advanced in explanation, but in the majority of cases the various aspects of the subject are too little known to warrant discussion. More experimental work is required to show how far environmental conditions on the one hand, and hereditary factors on the other, are responsible for this phenomenon. Those species which exhibit alary dimorphism afford material for the study of the inheritance of the two types of wings, but only in a few cases has this method of research been utilized.

This paper presents a reflection on a recently proposed solution to the problem of the free vibration response with the constant hysteretic damping model, that has been presented in some conferences in recent years, by the author himself and some of his colleagues. On the one hand, as expected, the subject has been received with natural criticism, mainly due to the well-known non-causal behaviour of the model in free vibration. On the other hand, it was not easy to understand what could be wrong in that proposal, as apparently everything was perfect from a mathematical point of view. The author decided that this subject deserved a more careful and detailed analysis and – in this kind of tutorial paper – the issue seems to have been clarified. It is concluded that the proposed solution involving the constant hysteretic damping corresponds in fact to an equivalent viscously damped model; it is therefore concluded that the application of the constant hysteretic damping to model the free vibration of practical engineering problems should be considered only in the perspective of an equivalent viscously damped model.

The article deals with the relatively new rules of Art. 434.1 the Civil Code of the Russian Federation on the conduct of negotiations. Taking into account the current wording of the said rule and the experience of foreign legislation on pre-contractual liability, the article argues for different theories justifying the nature of pre-contractual legal relations and liability and gives different positions of the authors on this issue. Proceeding from the doctrinal concept of obligation and characteristics of pre-contractual relations themselves the conclusion is made that these relations, firstly, are regulated by law and, secondly, they are not simply a legal relation but an obligation. It is based on certain actions of the negotiating partners that give rise to such an obliga-tion. As such, any action that is sufficiently certain (in some cases it may be required by law) and expresses the intention of the person to regard himself as negotiating with the addressee, who will in return perform the same sufficiently certain action, can be regarded as such. The specified characteristics of an action allow us to conclude that, from the point of view of classification of legal facts, this action is an act (because it is performed with a certain in-tention evident to other participants of civil turnover) and, moreover, it is also a transaction. Special rules of the Civil Code of the Russian Federation stipulate that the actions performed to enter into negotiations (for example, if the conclusion of a contract is binding on one party) or the actions of both partners entail legal consequences - the obligation to negotiate in good faith. The analysis of these legal relationships identifies three stages in their development, charac-terises them and attempts to answer more precisely the question of who can be a participant in the negotiation process depending on the stage of the negotiation process. The subject matter of an obligation arising during pre-contractual contacts will be actions aimed at negotiating and concluding a contract. The content of the obligation arising in the course of pre-contractual contacts, based on Art. 434.1 of the Civil Code will be the obligation to negotiate in good faith (paragraph 2 of the above rule). Assuming that the legislator provides an indicative list of actions that should fall within the scope of bad faith conduct, an indicative list of the "standard" of good faith conduct at the negotiation stage is given. This includes the obligation to provide full and truthful information to a party, including the reporting of circumstances that, due to the nature of the contract, must be brought to the attention of the other party (e.g. in a sale, all encumbrances on the subject of the contract must be reported). In addition, persons are obliged to negotiate only if they intend to conclude a contract, not to terminate negotiations suddenly and unjustifiably, and to take into account the rights and legitimate interests of the other party to the negotiation. The obligation under this obligation may also include a requirement not to disclose infor-mation obtained during the negotiation of the contract.

Violence has been a part of daily life in both traditional and digital media. Consequently, neither the existence of violence in the media nor the debates on this subject are new. On the other hand, the presentation of violence in fictional content should be viewed from a different point of view, especially in the context of aesthetization. Within this context, in this chapter, the serial of Penny Dreadful is analyzed. As analyzing method, Tahsin Yücel's model of the “space/time coordinates of narrative” is used. And the subject of “aestheticization of violence” is analyzed through a serial with the elements of person, space, and time. Thus, the role of not only physical beauty but also different components in the aestheticization of violence is examined.

In this paper, I explain the problem of the dreamer in the Zhuangzi. I aim to show that no difference exists between dreaming states and waking states because we have a fluctual relationship with these two stages. In both, “we are dreaming.” Put another way, from a psychoanalytical point of view, one stage penetrates the other and vice versa. The difference between dreaming and non-dreaming disappears because dreaming is a structural process. Also, from a psychoanalytical perspective, all confirmations and negations about dreams and non-dreams leads to one point: the being, or rather the becoming, of the subject. How does this solve the problem of the True Person/True Human Being (zhenren真人)? Does such a person have dreams or not? Does the True Person sleep without dreams, as we find in the Zhuangzi? From a psychoanalytic perspective, this is not possible. To prove this, I will present few passages from the Zhuangzi and offer a psychoanalytic explanation of them based on Jacques Lacan’s theory of the fantasy and desire.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

In human languages proverbs constitute a very important aspect of language use. Thus, they have been a subject of varying attention from different specialists: linguists and language users in general. Shakespeare is described as the most adroit user of proverbs in literature; therefore, his plays have been the subject of numerous scientific investigations, whereby from a linguistic point of view the focus has primarily been aimed at vocabulary and grammar. On the one hand, attention has been paid regularly to lexical items because Shakespeare is supposed to have been a great innovator of words due to his coinage of new lexemes and his usage of several unknown expressions. Linguistic studies have also been concerned with grammatical constructions which are typical of the English at Shakespeare’s time. Many writers employ proverbs in their works but Shakespeare is different in the way he employs proverbs which are used to serve different functions and to achieve different illocutionary acts. These proverbs are embedded in the flow of conversations and they may flout one or more than one of Grice‘s maxims. The present study aims at analyzing proverbs and explaining how far Grice’s cooperative principles (maxims) are abided by in Shakespeare’s proverbs as specified in the data. Proverbs are sometimes said to mean something else in addition to what is explicitly stated. Words may mean something beyond those intended by the speaker or the writer. These extra meanings might achieve or refer to different illocutionary acts. The study explores whether or not these illocutionary acts share certain structural features. In order to achieve the aims of the research, the following hypotheses have been proposed: Grice’s cooperative principle is frequently flouted in Shakespeare’s proverbs. The maxim of Quality seems to be flouted more than the other maxims. This maxim is mainly flouted by the use of metaphor. Shakespeare’s proverbs are also characterized by the use of the speech


The article is devoted to clarification of the phenomenon and logics included into the subject of forensic science. The author criticizes attempts of other commentators to extend the subject matter of this science as well as the statements about so-called crisis in forensic science in Russia. From the author’s point of view, there is no reason to speak about a crisis. At the same time, it is necessfry to specify the subject matter of forensic science. The author argues against extension of the subject matter of forensic science to the fields of civil procedure and arbitration. He believes that the main aim of science has been still to detect a trace picture of a crime. So, forensic science is primarily in the field of fighting crime. Only powerful bodies and officials carry out forensic activities. As for the other subjects (such as advocates) – they can only use the achievements of forensic sciences. The author analyzes positions of Russian (including Soviet) and German commentators. The analysis allowed the author to propose the definitions of forensic science and criminalistical (forensic) characteristics of crime.

The article examines the work of Vasily Polenov. The author presents Polenov’s artistic path as the dramatic choice between what is commonly called genre and landscape painting. From the philosophical point of view, the problem consists in concept of understanding art. On the one hand, the essence of art can be reduced to «what», to writing a story, a big sense. On the other hand, art can be understood as «painting for painting’s sake». In this sense, the tension in Polenov’s work arises between the paintings «Moscow Courtyard» and «Christ and the Sinner». The author notes that the way out of this dilemma is to understand art as the subject that reflects the non-objectifiable and devoid of anything essence. The article analyzes the philosophical meaning of Polenov’s paintings of the gospel cycle and provides a philosophical analysis of the artist’s nostalgic paintings. The author comes to the conclusion that Polenov’s paintings are the form that establishes an emotionally experiencing human being
